Swimming pool

ABSTRACT

A swimming pool construction having improved means for initially waterproofing adjoining sections of pool liners as well as to simplifying repair of damaged areas of joinder is disclosed. In pools of this general type bottom and side wall waterproof liners are held in position and rendered waterproof by shaped moldings clamped thereagainst. The invention simplifies installation and repair by providing the shaped moldings with ledges spaced from the pool walls or bottom to provide grooves or openings therebetween to receive edges of liners, sealing strips and sealing compound.

Primary Examiner-Henry K. Artis Attorney-Kurt Kelman [5 7] ABSTRACT Aswimming pool construction having improved means for initiallywaterproofing adjoining sections of pool liners as well as tosimplifying repair of damaged areas of joinder is disclosed. In pools ofthis general type bottom and side wall waterproof liners are held inposition and rendered waterproof by shaped moldings clampedthereagainst. The invention simplifies installation and repair byproviding the shaped moldings with ledges spaced from the pool walls orbottom to provide grooves or openings therebetween to receive edges, ofliners, sealing strips and sealing compound.

4 Claims, 1 Drawing Figure SWIMMING POOL The present invention relatesto improvements in prefabricated and transportable basins or pools.

U.S. Pat. No. 3,641,595 granted Feb. 15, 1972, to Hans Viessmann andentitled Prefabricated and Transportable Basins or Pools relates to aswimming pool having a waterproof bottom lining and verticallycorrugated side-wall sections whose upper and lower edges are held bysupporting members and which are lined on their inside surfaces with awaterproof lining with the waterproof linings in the area of the lowersupporting members, each of which have a flange at the bottom extendinginwards, being joined in waterproof connection by means of shapedmoldings.

One inherent problem with this type of pool whose waterproof walls,generally speaking, consist of individual sections, is the sealing ofthe junctions or points of joinder of the individual sections, in whichconsideration must be given to the facts that such types of pools alwayshave some degree of internal movement and that the sealing agentemployed must be easy and economical to manufacture and also be capableof quick and easy repair.

The shaped moldings which described in U.S. Pat. No. 3,641,595 are usedfor expediency in association with adhesive tapes, which somewhatcomplicates the construction because installing and repairing thesewatertight connections involves assembly and disassembly of the shapedmoldings. If the shaped moldings are used without the adhesive strips,then watertight sealing of the pool cannot be positively guaranteed.

it has also been proposed already by way of improve ment to solve thesealing problem in a simple manner by a method of providing the shapedmoldings with grooves or ledges opening towards the linings, and inwhich a sealing compound, for example silicone rubber, is filled.

With multi-sectional bottom linings, the lining-sections can also besealed by providing the shaped moldings downwardly facing grooves orledges which are open on the side facing the lining sections to receivea suitable sealing compound.

It has now been discovered that in the assembling of a pool both thewaterproofing and the appearance of these sectional molded sealings canbe more substantially improved if one does not fasten the shapedmoldings with screws whose heads also have to be sealed with a sealingcompound as has been the practice to date, but instead attachs theshaped moldings right from the beginning of the pool constructiondirectly to flanges on the sides of the pool tank, with the moldingsbeing shaped to provide grooves for clamping and for holding the sealingcompound, providing the advantage that the pool linings can be insertedand fastened in the grooves with sealing strips with the remainingportions of the grooves then being filled with a suitable sealingcompound.

The same procedure is applicable to both bottom and side wall moldings.

Using this form of construction it is possible to initially andcompletely assemble the pool without having regard to the waterproofingof points of contact and the problem of sealing them. After erection ofthe pool assembly the grooves are then filled by inserting sealingstrips and sealing compound.

lf subsequent damage to the pool should occur it is then not necessaryto disassemble the pool tank nor to remove theshaped moldings butinstead all that is requ- I ried is to clean the old sealing compoundfrom the damaged portion of the groove and to apply fresh sealingcompound.

The invention will now be described with reference to the accompanyingdrawing which is a diagrammatic illustration of one Fmbodiment of a poolbottom corner wedge.

The present invention relates to improvements in the pool constructionof the type described in U.S. Pat. No.

. ledges spaced from the bottom of the pool to provide longitudinalgrooves or openings to receive edges of adjacent bottom liner sectionsand sealing strips and sealing compound.

The shaped moldings 19 are firmly joined to the flanges 12, 17, forexample by means of rivets 21, and are delivered to the building sitealready fastened together.

The shaped moldings 19 are provided with ledges providing openings orgrooves facing the linings 4 and 5 (or the multi-sections of lining 5 asapplicable) and into which a sealing compound 45, for example siliconerubber, can be applied, after sealing strips 44 and the linings 4 and 5have been inserted to clamp the lining edges. The shaped molding 19 can,by way of example, be made of glass fibre reinforced polyester resin. Adecisive factor in the selection of the sealing compound 45 is that itshould retain a lasting degree of plasticity.

This type of sealing naturally can also be adapted for use inappropriate form for the upper rim support of the pool or even for thesealing of the periphery of the pool where it meets the edge of a poolpatio.

Obviously it is also possible to construct the shaped molding 19together with the supporting member 3 in one piece, in which case acentral portion 19' could be eliminated; In this case a side wallmolding 19" (see broken lines) would be provided on the upwardlydirected flange l7, and. a bottom molding provided on the inwardlydirected flange 12.

The embodiments of the invention in which an exclusive property orprivilege is claimed are defined as fol-.
